drift deposition values are included 

which account for more options 

available in the AgDRIFT model which 

allows for flexibility in the risk 

management process. These include: 

• All canopy types for orchard 

airblast sprayers, 

• All boom height and spray quality 

combinations available for groundboom 

sprayers, and 

• Different options for aircraft 

including consideration of helicopter 

use and differing spray qualities (e.g., 

coarse instead of fine to medium spray 

quality). 

V. Request for Comment 

EPA is providing an opportunity, 

through this notice, for the public to 

provide comments and input on any 

additional information that may impact 

the Agency’s assessment of spray drift 

in pesticide risk assessments. 

Specifically included within the 

Agency’s request for comments are the 

model-generated spray drift values as 

described in either or both of the draft 

guidance documents. 

With regards to the Ecological and 

Drinking Water Assessment Guidance, 

as discussed in Unit III., EPA currently 

uses spray drift estimates, developed in 

the 1990s, using best professional 

judgement: 5% (aerial application), 3% 

(air-blast application) and 1% (ground 

application) in selected terrestrial and 

Tier II aquatic exposure assessments. 

Based upon continued model 

refinements, EPA is revising this 

approach and is beginning to 

incorporate AgDRIFT model estimates 

in all tiers for terrestrial and aquatic 

environments to estimate more realistic 

exposure from spray drift deposition. 

This approach is more consistent with 

current approaches throughout OPP. 

EPA is seeking comment on this 

approach. 

While EPA does not intend to 

formally respond to all comments made, 

comments in response to this notice will 

be taken into consideration as EPA 

finalizes these guidance documents. If 

substantive comments are made that 

may substantially change the EPA’s 

consideration of spray drift in pesticide 

risk assessment, EPA will notify the 

public of these comments and describe 

how EPA has responded to them. 

VI. References

Committee (CASAC) Ozone Review 

Panel 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice. 

SUMMARY: The EPA Science Advisory 

Board (SAB) Staff Office announces a 

public meeting of the CASAC Ozone 

Review Panel to conduct a peer review 

of three draft EPA documents: (1) Health 

Risk and Exposure Assessment for 

Ozone—Second External Review Draft 

(January 2014), (2) Welfare Risk and 

Exposure Assessment for Ozone— 

Second External Review Draft (January 

2014) and (3) Policy Assessment for the 

Review of the Ozone National Ambient 

Air Quality Standards—Second 

External Review Draft (January 2014). 

DATES: The CASAC Ozone Review Panel 

meeting will be held on Tuesday, March 

25, 2014 from 9:00 a.m. to 5:30 p.m. 

(Eastern Time), Wednesday, March 26, 

2014 from 8:30 a.m. to 5:30 p.m.

St., Chapel Hill, NC 27516. 

FOR FURTHER INFORMATION CONTACT: Any 

member of the public who wants further 

information concerning the public 

meeting may contact Dr. Holly 

Stallworth, Designated Federal Officer 

(DFO), via telephone at (202) 564–2073 

or email at stallworth.holly@epa.gov. 

General information concerning the 

CASAC can be found on the EPA Web 

site at http://www.epa.gov/casac. 

SUPPLEMENTARY INFORMATION: The 

CASAC was established pursuant to the 

Clean Air Act (CAA) Amendments of 

1977, codified at 42 U.S.C. 7409D(d)(2), 

to provide advice, information, and 

recommendations to the Administrator 

on the scientific and technical aspects of 

issues related to the criteria for air 

quality standards, research related to air 

quality, sources of air pollution, and the 

strategies to attain and maintain air 

quality standards and to prevent 

significant deterioration of air quality. 

The CASAC is a Federal Advisory 

Committee chartered under the Federal 

Advisory Committee Act (FACA), 5 

U.S.C., App. 2. Pursuant to FACA and 

EPA policy, notice is hereby given that 

the chartered CASAC augmented with 

additional experts, known as the 

CASAC Ozone Review Panel, will hold 

a public meeting to peer review EPA’s 

draft documents referenced above. 

These EPA draft documents are 

prepared as part of the agency’s review 

of the National Ambient Air Quality 

Standards (NAAQS) for ozone. 

Section 109(d)(1) of the CAA requires 

that the Agency periodically review and 

revise, as appropriate, the air quality 

criteria and the NAAQS for the six 

‘‘criteria’’ air pollutants, including 

ozone. EPA is currently reviewing the 

primary (health-based) and secondary 

(welfare-based) NAAQS for ozone. The 

CASAC previously reviewed EPA’s 

Health Risk and Exposure Assessment 

for Ozone (First External Review Draft— 

Updated August 2012) and Welfare Risk 

and Exposure Assessment for Ozone 

(First External Review Draft—Updated 

August 2012). CASAC’s comments on 

both of these documents are reported in 

a letter to the EPA Administrator, dated 

November 19, 2012 (EPA–CASAC–13– 


tkelley on DSK3SPTVN1PROD with NOTICES
4694 Federal Register / Vol. 79, No. 19 / Wednesday, January 29, 2014 / Notices 

002). CASAC also previously reviewed 

EPA’s Policy Assessment for the Review 

of the Ozone National Ambient Air 

Quality Standards (First External 

Review Draft—August 2012) as reported 

in a letter to the EPA Administrator, 

dated November 26, 2012 (EPA– 

CASAC–13–003). 

The CASAC Ozone Review Panel will 

comply with the provisions of FACA 

and all appropriate SAB Staff Office 

procedural policies. 

Technical Contacts: Any technical 

questions concerning the Health Risk 

and Exposure Assessment for Ozone— 

Second External Review Draft (January 

2014) or concerning the Welfare Risk 

and Exposure Assessment for Ozone— 

Second External Review Draft (January 

2014) should be directed to Dr. Bryan 

Hubbell (hubbell.bryan@epa.gov). Any 

questions concerning the Policy 

Assessment for the Review of the Ozone 

National Ambient Air Quality 

Standards—Second External Review 

Draft (January 2014) should be directed 

to Ms. Susan Lyon Stone 

(stone.susan@epa.gov). 

Availability of Meeting Materials: 

Prior to the meeting, the review 

documents, agenda and other materials 

will be accessible through the calendar 

link on the blue navigation bar at http:// 

www.epa.gov/casac/. 

Procedures for Providing Public Input: 

Public comment for consideration by 

EPA’s federal advisory committees and 

panels has a different purpose from 

public comment provided to EPA 

program offices. Therefore, the process 

for submitting comments to a federal 

advisory committee is different from the 

process used to submit comments to an 

EPA program office. Federal advisory 

committees and panels, including 

scientific advisory committees, provide 

independent advice to EPA. Members of 

the public can submit relevant 

comments for a federal advisory 

committee to consider pertaining to 

EPA’s charge to the committee or review 

materials. Input from the public to the 

CASAC will have the most impact if it 

provides specific scientific, technical 

information or analysis or if it relates to 

the clarity or accuracy of the technical 

information for the CASAC’s 

consideration. Members of the public 

wishing to provide comment should 

contact the Designated Federal Officer 

directly. Oral Statements: In general, 

individuals or groups requesting an oral 

presentation at a public meeting will be 

limited to five minutes. Interested 

parties should contact Dr. Stallworth, 

DFO, in writing (preferably via email) at 

the contact information noted above by 

March 13, 2014, to be placed on the list 

of public speakers for the meeting. 

Written Statements: Written statements 

should be submitted to the DFO via 

email at the contact information noted 

above by March 13, 2014 for the meeting 

so that the information may be made 

available to the CASAC Panel for their 

consideration. Written statements 

should be supplied in one of the 

following electronic formats: Adobe 

Acrobat PDF, MS Word, MS 

PowerPoint, or Rich Text files in IBM– 

PC/Windows 98/2000/XP format. It is 

the SAB Staff Office general policy to 

post public comments on the Web page 

for the advisory meeting or 

teleconference. Submitters are requested 

to provide an unsigned version of each 

document because the SAB Staff Office 

does not publish documents with 

signatures on its Web sites. Members of 

the public should be aware that their 

personal contact information, if 

included in any written comments, may 

be posted to the CASAC Web site. 

Copyrighted material will not be posted 

without explicit permission of the 

copyright holder. 

Accessibility: The public can view the 

March 25–27, 2014 meeting via a noninteractive webcast that will be 

broadcast on the internet. The 

connection information to view the 

meeting via webcast will be provided on 

the SAB Web site at http:// 

www.epa.gov/casac in advance of the 

meeting. For information on access or 

services for individuals with 

disabilities, please contact Dr. Holly 

Stallworth at (202) 564–2073 or 

stallworth.holly@epa.gov. To request 

accommodation of a disability, please 

contact Dr. Stallworth preferably at least 

ten days prior to the meeting to give 

EPA as much time as possible to process 

your request.
